The Adar oilfield, also known as the Adar Yale, Adar Yeil or Adaril field, is an oilfield situated in the Melut Basin in South Sudan estimated to contain about 276 million barrels (43,900,000 m3) of oil. The Chevron Corporation discovered the Adar Yale field in 1981, shortly before the start of the Second Sudanese Civil War (1983–2005). Soon after Chevron had suspended operations in 1984, Sudanese government troops began attacking civilian settlements in the area, burning the houses and driving the people away, and in the late 1990s, Nuer militias from Nasir helped the army in clearing away the people to make way for the roads and infrastructure of the oilfield.
